Health Insurance Captives
Where a group of self-funded employers pool their risk in a jointly owned insurance company.
A health insurance captive is a structure in which a group of employers jointly own or participate in an insurance company (the “captive”) that helps finance and manage the risk of their self-funded health plans.
How health insurance captives work
--> An employer has a self-funded health plan
--> The employer joins a captive with other employers
--> Each employer pays claims for its own employees up to a certain level, plus premiums to the captive for a layer of larger claims
--> The captive purchases stop-loss insurance from a commercial insurer for catastrophic claims above the captive’s risk layer
In simple terms: Self-funded employers pool part of their risk in a jointly owned captive that covers a middle layer of claims — above what each employer pays and below where the stop-loss carrier takes over.
Example: how the claim layers work
--> Employer pays claims from $0–$75,000
--> Captive pays claims from $75,000–$500,000
--> Commercial stop-loss carrier pays claims above $500,000
Based on a $75,000 specific stop-loss deductible per member per year. The exact layers vary by captive.
CuatroBenefits Insights:
Small and mid-sized employers with self-funded health plans have seen the wisdom in taking control while spreading their risk to a stop-loss carrier. A health insurance captive allows them to spread that risk even further. Moreover, some captives have the scale to secure and provide members with access to Fortune 500 level resources and solutions that help to improve member health while lowering plan costs.
Employers considering a captive strategy need to make sure that the captive they choose is well-managed and has a track record of success. Otherwise, they might face additional costs should the captive have higher claims than expected. Employers should also be willing to commit to managing their risk and implementing strategies to improve plan performance over time. To that end, they should consider what their captive can provide to help with cost control.
Who is a good fit?
--> Have 50 to several thousand employees
--> Are already self-funded or considering self-funding
--> Have relatively stable claims experience
--> Want more control over healthcare costs
--> Can tolerate some risk in exchange for potential savings
Potential advantages
--> More control over health plan costs
--> More stable renewals over time
--> Ability to spread risk among multiple employers
--> Flexibility to integrate cost-saving solutions like data analytics, population health programs, direct contracting for surgery and imaging, and employer-advantaged prescription benefit management
--> Access to underwriting profits if claims are favorable
Potential disadvantages
--> Possible assessments if captive losses are higher than expected
--> Potentially less predictable costs in bad claim years
--> Requires commitment to risk management and wellness efforts
--> Not every employer qualifies
Types of health captives
--> Single-parent captive — One large employer owns the captive (e.g., Walmart, Caterpillar, FedEx, Microsoft)
--> Group captive — Multiple unrelated employers share ownership and risk
--> Cell or protected-cell captive — Employers participate in separate “cells” within a larger captive structure
--> Association captive — Members of an industry association participate together
Health Insurance Captive FAQs:
With straight self-funding, your organization shoulders its claims risk alone, up to your stop-loss layer. In a captive, you join with other like-minded employers and share a middle layer of risk together. That pooling smooths out the ups and downs — a rough year for your group is cushioned by the group as a whole — and it gives smaller employers access to the kind of scale, resources, and pricing usually reserved for the biggest companies.
In simple terms: it's self-funding with partners instead of going it alone.
It's the threshold that separates the claims you're responsible for from the claims that get protected. For example, with a $75,000 specific deductible, your plan covers an individual's claims up to $75,000; anything above that for that person is picked up by the next layer. In a captive, claims above your deductible flow into the shared captive layer, and truly catastrophic claims are covered by commercial stop-loss above that. Setting that deductible is really about choosing how much risk fits your comfort zone and budget, and that's something we'll help you think through.
This is the honest tradeoff with captives. In a strong year, members can share in the savings; in a rough year, there can be additional assessments if the group's losses run higher than expected. That's why choosing a well-managed captive with a solid track record matters so much, and why captives work best for employers willing to commit to managing their risk and improving plan performance over time. We only point clients toward captives we'd be comfortable joining ourselves.
Captives tend to fit employers who are already self-funded or seriously considering it, have relatively stable claims, want more control over their healthcare costs, and can tolerate some year-to-year variability in exchange for long-term savings. There's room for a wide range of employer sizes. The best way to know is a real conversation about your claims history, risk tolerance, and goals, and we're glad to have it.
